It has a user interface, +control functions, setting values and a means of defining the location where +the image or video clip is to be saved. It will also store the image and video +settings. + +The Camera class contains an instance of \l {QCamera}, the API class interface to +the hardware. It also has an instance of \l {QCameraImageCapture} to take still images +and an instance of \l {QMediaRecorder} to record video. It also contains the user +interface object. + +The Camera constructor does some basic initialization. The camera object is +set to '0', the user interface is initialized and UI signal are connected to +slots that react to the triggering event. However, most of the work is done when +the \e{setCamera()} function is called, passing in a \l {QByteArray}. + +\e{setCamera()} sets up various connections between the user interface and the functionality +of the Camera class using signals and slots. It also instantiates and initializes the \l {QCamera}, +\l {QCameraImageCapture} and \l {QMediaRecorder} objects mentioned above. The still +and video recording visual tabs are enabled and finally the +\l {QCamera::start()}{start()} function of the \l{QCamera} object is called. + +Now that the camera is ready for user commands it waits for a suitable event. +Such an event will be the key press of either the \l {Qt::Key_CameraFocus} or +\l {Qt::Key_Camera} buttons on the application window. Camera focus will +simply display the viewfinder and lock the camera settings. Key_Camera will +either call \e{takeImage()} if the \l {QCamera::captureMode()}{captureMode()} +is QCamera::CaptureStillImage, or if the capture mode is for video then one +of two actions will occur. If the recording state shows that we are currently +recording then the \e{stop()} function is called resulting in a call to +\l {QCamera::stop()}, whereas if we are not recording then a video recording +is started with a call to \l {QMediaRecorder::record()}. + +\image camera-example.png + +*/ + + diff --git a/examples/multimediawidgets/camera/imagesettings.cpp b/examples/multimediawidgets/camera/imagesettings.cpp new file mode 100644 index 000000000..566a1260b --- /dev/null +++ b/examples/multimediawidgets/camera/imagesettings.cpp @@ -0,0 +1,125 @@ +/**************************************************************************** +** +** Copyright (C) 2012 Digia Plc and/or its subsidiary(-ies). +** Contact: http://www.qt-project.org/legal +** +** This file is part of the examples of the Qt Toolkit. +** +** $QT_BEGIN_LICENSE:BSD$ +** You may use this file under the terms of the BSD license as follows: +** +** "Redistribution and use in source and binary forms, with or without +** modification, are permitted provided that the following conditions are +** met: +** * Redistributions of source code must retain the above copyright +** notice, this list of conditions and the following disclaimer. +** * Redistributions in binary form must reproduce the above copyright +** notice, this list of conditions and the following disclaimer in +** the documentation and/or other materials provided with the +** distribution. +** * Neither the name of Digia Plc and its Subsidiary(-ies) nor the names +** of its contributors may be used to endorse or promote products derived +** from this software without specific prior written permission. +** +** +** THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS +** "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT +** LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR +** A PARTICULAR PURPOSE ARE DISCLAIMED.

We can go to Full Screen mode with a single + button click, and back again. Or if we press the "Color Options" dialog + button we can have access to more subtle influences. The dialog has a + set of sliders so that we can change the brightness, contrast, hue and + saturation of the video being watched.
